Galaxy Song

Just remember that you're standing on a planet that's evolving
Revolving at 900 miles an hour
It's orbiting at 19 miles a second, so it's reckoned
A sun that is the source of all our power

The Sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral orb, at 40,000 miles an hour
Of the galaxy, we call the Milky Way

Our galaxy itself contains a hundred billion stars
It's a 100,000 light years side to side
It bulges in the middle, 16,000 light years thick
But out by us it's just 3,000 light years wide

We're 30,000 light years from galactic central point
We go round every 200,000,000 years
And our galaxy is only one of millions of billions
In this amazing and expanding universe

Our universe itself keeps on expanding and expanding
In all of the directions it can whiz
As fast as it can go, the speed of light you know
12,000,000 miles a minute, and that's the fastest speed there is

So, remember when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
'Cause I'm afraid that we've been cheated here on Earth
